Joshua Jackson: I know how 'Fringe' ends

"Fringe" will have its biggest Comic-Con stage ever on Sunday (July 15) when the cast and producers greet fans in the San Diego Convention Center's massive Hall H. And it's likely just about all those fans will want to know about the show's ending.

They can ask series star
Joshua Jackson -- because he says he knows where "Fringe's" final season is headed.

"My show being what it is, I can't tell you, but we have a really distinct ... and very cool wrapping up of the entire series," Jackson
tells The Hollywood Reporter in a pre-Comic-Con roundtable with several other actors.

That's something of a surprise, as in the past the "Fringe" powers that be tended to keep story details secret, even from the cast. Jackson says showrunner
J.H. Wyman "has been kind of shockingly forthcoming, because our show is usually pretty impenetrable. But this is the last year, and I guess it's a new leaf. He was like, 'I want everybody engaged. I want everybody to know exactly what they're doing.'"

"You're not leaving this room until you tell us," jokes
Lucy Liu, one of the other roundtable participants.

"Part of what's fun about a television show is that people get to fill in the gaps for themselves of who these characters are and the stories that we don't get to see," Jackson says. "But once you come up to an ending, you sort of tell them where everybody finishes up. That being said, it's a big, massive sci-fi set piece at the end, but with a really important, finale-esque emotional center to it. I sound like a producer now, but it is true."

The "Fringe" Comic-Con session is at 10 a.m. Sunday. The show's final season kicks off Sept. 28.
